Location, location, location! Natalie's place is not only 2 minutes by foot from BTS Ratchadamri, but is also walking distance from Siam Paragon, CentralWorld, Central Embassy and Lumphini Park. You could also walk to Silom/Saladaeng and MBK if you saw fit—I did many times.
The space itself is stylish and simple; the building is definitely a bit retro. But the staff are courteous, and the on-site gym and laundry shop are really convenient.
I will definitely stay here next time!
